The HTWU platform pairs a removable U-tube bundle with proven shell-side baffling, and this configuration applies that design to high-temperature water heating. High-temperature water flows through the tube side, so the heads rather than the shell set the pressure limit. Dimensionally it is a 12-inch shell unit, 48-inch shell length, and roughly 54 inches overall in a 4-pass arrangement. That works out to about 78 square feet of heat transfer surface on 3/4-inch O.D. tubes. That combination is cataloged as 5-268-12-048-002. As furnished, materials include cast iron bonnets, steel shell, copper tubes, and steel tubesheets. Design ratings run to 150 PSI on the shell side, 400 PSI on the tube side, and 375°F maximum temperature.
